Embodiment Construction

[0036] Hereinafter, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. According to these detailed descriptions, those skilled in the art can clearly understand the present application and can implement the present application. Without departing from the principle of the present application, the features in different embodiments can be combined to obtain new implementations, or some features in certain embodiments can be replaced to obtain other preferred implementations.

[0037] Ultrasonic levitation is caused by the sound pressure nodes of standing waves. After the standing wave is formed, an upward sound pressure and a downward sound pressure are generated, which are sinusoidally distributed. The place where the sound pressure in the upward direction and the sound pressure in the downward direction intersect is the sound pressure node, that is, the point where the sound pressure is theoretically zero. A...

Abstract

The invention relates to the technical field of water drop icing and ice prevention, in particular to a water drop icing visualization experiment device and application thereof. At present, observation of water drop suspension in-phase icing cannot be carried out due to frosting and temperature limitation. The invention provides a water drop icing visualization experiment device which comprises a cabin door, the cabin door is connected with a shell, a temperature adjusting assembly is arranged in the shell, a suspension liquid drop generating assembly and a liquid drop generator are arranged in the shell, and the liquid drop generator is used in cooperation with the suspension liquid drop generating assembly; the cabin door is provided with an observation window, the observation window is connected with a vacuumizing assembly, and the cabin door can be connected with the shell in a sealed mode. The suspension freezing process observation of water drops in nitrogen environments at different temperatures can be realized, the size of the water drops, the suspension position of the water drops and the internal temperature of the cold cavity can be changed, and the suspension freezing process of the water drops can be obtained through experiments.

Description

technical field [0001] The present application relates to the field of water drop icing and anti-icing technology, in particular to a water drop icing visualization experiment device and its application. Background technique [0002] In nature, icing is ubiquitous and affects many aspects of life. For the anti-icing goals of aircraft, plants, and man-made structures, as well as to control freezing and solidification processes in industry, there is an urgent need to unravel the physical mechanisms involved in these phenomena. In particular, the freezing mode of impinging droplets is critical to many industrial processes, such as the energy required for deicing, the quality of thermal spray coatings, and spray freeze-drying for the production of milk powder, pharmaceutical proteins, and influenza vaccines. For the icing of water droplets on cold surfaces, the existing experimental platform can already realize its data collection and post-processing. [0003] The icing of wat...
